对于沼泽等松软地面,在日本常用“湿地”一词加以概括。它是指一般通用施工机械,在其上作业时,容易沉陷、打滑而不能充分发挥固有性能者。日本的湿地分布于沿海地区,近年来多已开发;有些是战后日本为解决粮食问题而进行的围湖垦田。如我们这次考察团所到的秋田县八郎潟、石川县河北潟等地,原来都是一些较大的浅湖,经过排水后围垦而成的,日本称之为“干拓”地。 For soft ground such as swamps, the term “wetland” is commonly used in Japan. It refers to a general general-purpose construction machine. When it is operated on it, it is easy to sink and slip and cannot fully exert its inherent performance. Japan’s wetlands are distributed in the coastal areas and have been developed in recent years; some are post-war Japan to solve food problems. For example, the visits to Hachigaya, Akita, and Ishikawa Prefecture, Hebei Province, which were visited by our delegation, were originally large shallow lakes that were reclaimed after being drained, which Japan called “dry extension”.
